The shield function is important, and accurate placement is required when installing the shield plate used for this purpose. For example, in an electronic tuner, a shield plate is interposed to electromagnetically shield a portion of a wiring body housed in a chassis base frame from other portions. The shield plate is fitted onto and held by the printed circuit board of the wiring body and the chassis base frame, and fixed by soldering.

れる。 In such a shield structure, for example, as shown in FIGS. 3 and 4, a wiring body of a printed circuit board 2 is housed in a chassis base frame 1, and a peripheral grounding pattern 3 of the circuit board is connected to the chassis base frame 1. A shield plate 5 having an L-shaped cross section and electromechanically bonded with solder 4 is disposed between the base frame 1 and the central ground pattern 6 of the board. The shield plate 5 consists of a flat main part 5a and a bent part 5b, one end of which has a tongue piece 5c of the bent part 5b penetrating the printed circuit board 2 and connected to the central grounding pattern 6 with solder 4, and the other end. The ends are a pair of protrusions 1a of the frame 1,
1b and connected with solder 4. Prior to soldering, the shield plate 5 is attached to the frame 1 by inserting the tongue piece 5c into the through hole 2a of the printed circuit board 2.
It is fitted into the gap between the protrusions 1a and 1b and is temporarily held.

の容易性と半田処理の確実性が必要とされる。 By the way, the above-mentioned soldering is generally performed by assembling the wiring components on the printed circuit board 2 on the frame 1, temporarily fixing the components using a jig, and then soldering them all at once using a solder dip method. Therefore, ease of assembly of each component and reliability of soldering are required.

理中に位置ずれを起し易い。Problems to be Solved by the Invention The important problem in the above-mentioned shield structure was the assembling work of the shield plate 5 and the position regulation until it was temporarily fixed and soldered. In other words, the temporary fixing of the shield plate 5 may be uncertain, or the shield plate 5 may be displaced and fall off before soldering. This is done after inserting the tongue piece 5c into the through hole 2a of the printed circuit board 2 in order to assemble the shield plate 5.
The shield plate 5 is deformed because it is inserted between the pair of locking portions 1a and 1b by pushing along the slope of one of the locking portions 1a with the end surface of the shield plate a in contact with the inner wall of the base frame 1. In particular, as the bending angle becomes smaller, the elastic contact of the tongue piece 5c decreases, which tends to cause misalignment during soldering.

ド構体を提供する。Means for Solving the Problems The present invention is to solder the peripheral side grounding pattern of the printed circuit board to the chassis base frame, and electrically connect the center side grounding pattern partially through a spaced shield plate. In this case, as a structure for attaching the shield plate to the chassis base frame, a protrusion is provided on the frame, a locking portion that engages with the protrusion is provided on the shield plate, and both are accurately soldered and fixed at a predetermined position. In particular, a shield structure is provided that is easy to assemble by forming the locking portion of the shield plate by cutting and raising it.
